Referring to a wooden plaque that the rapper sent him, celebrating the success of the song, Mr. Trump tweeted: "Little @MacMiller I don't need your praise ... just pay me the money you owe."

In a flurry of tweets, he also posted: "Little @MacMiller, I'm now going to teach you a big boy lesson about lawsuits and finance. You ungrateful dog! and Little @MacMiller I have more hair than you do and there's a slight age difference."

"i'm not trying to put any negative energy into the world.@realDonaldTrump let's be friends," Miller, who is touring in Austria, posted Friday on Twitter.

The song, which has 75 million hits on YouTube, is not about Mr. Trump; rather, it uses the financier as a symbol of monetary success.

Mr. Trump's Twitter blitz may have been fueled by Miller's recent interview with Complex magazine (http://www.complex.com/music/2013/01/mac-miller-dumps-on-donald-trump, be advised the video contains harsh language) in which the rapper harshly criticizes Mr. Trump's behavior during the presidential campaign and also says, "The thing that bothers me the most is that he always says things like, '75 million views on the song "Donald Trump," Mac Miller you're welcome.' I could've said, 'Take over the world when I'm on my Bill Gates [stuff].' It doesn't matter ..."
